SEQUENCE LISTING

The present application is being filed along with a Sequence Listing in electronic format. The Sequence Listing is provided as a file entitled CORE0132USASEQ_ST25.txt, created May 8, 2017, which is 72 Kb in size. The information in the electronic format of the sequence listing is incorporated herein by reference in its entirety.

BACKGROUND

Translation of a polypeptide or protein encoded by an mRNA typically begins at the start codon of the primary open reading frame (pORF) of the mRNA. Some mRNA transcripts also comprise one or more additional start codons. Such additional start codons may be upstream of the pORF start codon. Such an additional start codon that is upstream of a pORF is referred to as an upstream open reading frame (uORF) start site. The potential role of additional start sites in regulating translation of pORF protein products has been discussed previously (see Barbosa et al. PLOS Genetics. 9, e1003529 (2013)) which is hereby incorporated by reference in its entirety. Mutations that introduce or eliminate an additional start codon (a uORF start codon) in a transcript can disrupt regulation of its translation and can lead to disease (see Calvo et al. Proc. Natl. Acad. Sci. 106, 7507 (2009)) which is hereby incorporated by reference in its entirety.

Antisense technology is an effective means for modulating the expression of one or more specific gene products and can therefore prove to be uniquely useful in a number of therapeutic, diagnostic, and research applications. Chemically modified nucleosides may be incorporated into antisense compounds to enhance one or more properties, such as nuclease resistance, pharmacokinetics or affinity for a target nucleic acid. In 1998, the antisense compound, Vitravene® (fomivirsen; developed by Isis Pharmaceuticals Inc., Carlsbad, Calif.) was the first antisense drug to achieve marketing clearance from the U.S. Food and Drug Administration (FDA), and is currently a treatment of cytomegalovirus (CMV)-induced retinitis in AIDS patients. For another example, an antisense compound targeting ApoB, KYNAMRO™, has been approved by the U.S. Food and Drug Administration (FDA) as an adjunct treatment to lipid-lowering medications and diet to reduce low density lipoprotein-cholesterol (LDL-C), ApoB, total cholesterol (TC), and non-high density lipoprotein-cholesterol (non HDL-C) in patients with homozygous familial hypercholesterolemia (HoFH).

SUMMARY

The present disclosure provides compounds that interact with the 5′-UTR of a target transcript to increase translation of a target protein. It was discovered that certain compounds that interact with the 5′-UTR can increase translation of a given target transcript. For example, in certain embodiments, the present disclosure provides antisense compounds targeted to one or more regions of the 5′-UTR. These regions of the 5′-UTR may include a translation suppression element, such as a stem-loop structure or a uORF. When the antisense compounds interact with the translation suppression element in the 5′-UTR, the antisense compounds increase translation of the target transcript. One aspect of the invention is the increase in expression through contacting a cell with an agent targets a translation suppression element in the 5′-UTR. In certain embodiments, antisense compounds targeted to the 5′-UTR increase expression of a given target protein by disrupting a translation suppression element within the 5′-UTR.

Antisense oligonucleotide technology has been used most often to reduce the amount an mRNA via antisense induced RNase H cleavage or to alter splicing of a pre-mRNA transcript in a cell. In certain embodiments, the present disclosure provides antisense compounds that increase expression of a target protein in a cell. In this manner, antisense oligonucleotides may be used to increase the expression of a desired protein in a cell. In certain embodiments, an increase in the expression of a target protein in a cell is achieved by having the antisense compound reduce ribosomal recognition of one or more upstream open reading frames. In certain embodiments, recognition of an upstream open reading frame reduces expression of a target protein in a cell. Therefore, in certain embodiments, targeting the upstream open reading frame, or the nucleobase sequence upstream or downstream of the upstream open reading frame, reduces ribosomal recognition of the upstream open reading frame and thereby increases expression of one or more target proteins. Therefore, in certain embodiments, targeting the upstream open reading frame, or the nucleobase sequence upstream or downstream of the upstream open reading frame, reduces ribosomal recognition of the upstream open reading frame and thereby increases ribosomal recognition of a start codon in the primary open reading frame.

In certain embodiments, the present invention uses antisense compounds to increase expression of a target protein. In certain instances, a transcript encoding a protein of interest includes a pORF and one or more additional start sites, such as uORF start sites. In certain embodiments, the present disclosure provides modified oligonucleotides that are complementary to the target transcript at or near such uORF start sites. Antisense compounds designed to reduce the amount of a target protein typically induce cleavage of the target transcript (e.g., through recruitment of RNase H). In contrast, in certain embodiments of the present invention, modified oligonucleotides are not designed to elicit cleavage. Rather, in certain such embodiments, the modified oligonucleotides of the present invention mask a uORF start site in favor of increased translation at a pORF start site. In certain embodiments, the modified oligonucleotides of the present invention disrupt initiation of translation at a uORF start site and, in certain embodiments, thereby increase translation of the target protein. In certain embodiments, modified oligonucleotides of the present invention disrupt the regulatory function of the 5′-UTR. In certain such embodiments, translation of the desired protein is increased. In certain embodiments, modified oligonucleotides of the present invention recruit proteins to the transcript that interfere with initiation of translation at the uORF start site. In certain embodiments, antisense compounds of the invention result in decreased translation of a uORF polypeptide.

Accordingly, unless otherwise indicated, a “nucleoside having a modification of a first type” may be an unmodified nucleoside.

As used herein, “differently modified” mean chemical modifications or chemical substituents that are different from one another, including absence of modifications. Thus, for example, a MOE nucleoside and an unmodified DNA nucleoside are “differently modified,” even though the DNA nucleoside is unmodified. Likewise, DNA and RNA are “differently modified,” even though both are naturally-occurring unmodified nucleosides. Nucleosides that are the same but for comprising different nucleobases are not differently modified. For example, a nucleoside comprising a 2′-OMe modified sugar and an unmodified adenine nucleobase and a nucleoside comprising a 2′-OMe modified sugar and an unmodified thymine nucleobase are not differently modified.

As used herein, “the same type of modifications” refers to modifications that are the same as one another, including absence of modifications. Thus, for example, two unmodified DNA nucleoside have “the same type of modification,” even though the DNA nucleoside is unmodified. Such nucleosides having the same type modification may comprise different nucleobases.

In certain embodiments, bicyclic sugar moieties and nucleosides incorporating such bicyclic sugar moieties are further defined by isomeric configuration. For example, a nucleoside comprising a 4′-2′ methylene-oxy bridge, may be in the α-L configuration or in the β-D configuration. Previously, α-L-methyleneoxy (4′-CH₂—O-2′) bicyclic nucleosides have been incorporated into antisense oligonucleotides that showed antisense activity (Frieden et al., Nucleic Acids Research, 2003, 21, 6365-6372).

In certain embodiments, substituted sugar moieties comprise one or more non-bridging sugar substituent and one or more bridging sugar substituent (e.g., 5′-substituted and 4′-2′ bridged sugars). (see, PCT International Application WO 2007/134181, published on Nov. 22, 2007, wherein LNA is substituted with, for example, a 5′-methyl or a 5′-vinyl group).

In certain embodiments, modified sugar moieties are sugar surrogates. In certain such embodiments, the oxygen atom of the naturally occurring sugar is substituted, e.g., with a sulfer, carbon or nitrogen atom. In certain such embodiments, such modified sugar moiety also comprises bridging and/or non-bridging substituents as described above. For example, certain sugar surrogates comprise a 4′-sulfer atom and a substitution at the 2-position (see, e.g., published U.S. Patent Application US2005/0130923, published on Jun. 16, 2005) and/or the 5′ position. By way of additional example, carbocyclic bicyclic nucleosides having a 4′-2′ bridge have been described (see, e.g., Freier et al., Nucleic Acids Research, 1997, 25(22), 4429-4443 and Albaek et al., J. Org. Chem., 2006, 71, 7731-7740).

In certain embodiments, sugar surrogates comprise rings having other than 5-atoms. For example, in certain embodiments, a sugar surrogate comprises a six-membered tetrahydropyran. Such tetrahydropyrans may be further modified or substituted. Nucleosides comprising such modified tetrahydropyrans include, but are not limited to, hexitol nucleic acid (HNA), anitol nucleic acid (ANA), manitol nucleic acid (MNA) (see Leumann, C J. Bioorg. & Med. Chem. (2002) 10:841-854), fluoro HNA (F-HNA), and those compounds having Formula VII:

wherein independently for each of said at least one tetrahydropyran nucleoside analog of Formula VII:

Bx is a nucleobase moiety;

T₃ and T₄ are each, independently, an intemucleoside linking group linking the tetrahydropyran nucleoside analog to the antisense compound or one of T₃ and T₄ is an intemucleoside linking group linking the tetrahydropyran nucleoside analog to the antisense compound and the other of T₃ and T₄ is H, a hydroxyl protecting group, a linked conjugate group, or a 5′ or 3′-terminal group; q₁, q₂, q₃, q₄, q₅, q₆ and q₇ are each, independently, H, C₁-C₆ alkyl, substituted C₁-C₆ alkyl, C₂-C₆ alkenyl, substituted C₂-C₆ alkenyl, C₂-C₆ alkynyl, or substituted C₂-C₆ alkynyl; and

each of R₁ and R₂ is independently selected from among: hydrogen, halogen, substituted or unsubstituted alkoxy, NJ₁J₂, SJ₁, N₃, OC(═X)J₁, OC(═X)NJ₁J₂, NJ₃C(═X)NJ₁J₂, and CN, wherein X is O, S or NJ₁, and each J₁, J₂, and J₃ is, independently, H or C₁-C₆ alkyl.

In certain embodiments, the modified THP nucleosides of Formula VII are provided wherein q₁, q₂, q₃, q₄, q₅, q₆ and q₇ are each H. In certain embodiments, at least one of q₁, q₂, q₃, q₄, q₅, q₆ and q₇ is other than H. In certain embodiments, at least one of q₁, q₂, q₃, q₄, q₅, q₆ and q₇ is methyl. In certain embodiments, THP nucleosides of Formula VII are provided wherein one of R₁ and R₂ is F. In certain embodiments, R₁ is fluoro and R₂ is H, R₁ is methoxy and R₂ is H, and R₁ is methoxyethoxy and R₂ is H.

Many other bicyclic and tricyclic sugar and sugar surrogate ring systems are known in the art that can be used to modify nucleosides (see, e.g., review article: Leumann, J. C, Bioorganic & Medicinal Chemistry, 2002, 10, 841-854).

In certain embodiments, sugar surrogates comprise rings having more than 5 atoms and more than one heteroatom. For example nucleosides comprising morpholino sugar moieties and their use in oligomenc compounds has been reported (see for example: Braasch et al., Biochemistry, 2002, 41, 4503-4510; and U.S. Pat. Nos. 5,698,685; 5,166,315; 5,185,444; and 5,034,506). As used here, the term “morpholino” means a sugar surrogate having the following structure:

In certain embodiments, morpholinos may be modified, for example by adding or altering various substituent groups from the above morpholino structure. Such sugar surrogates are referred to herein as “modifed morpholinos.”

Combinations of modifications are also provided without limitation, such as 2′-F-5′-methyl substituted nucleosides (see PCT International Application WO 2008/101157 Published on Aug. 21, 2008 for other disclosed 5′, 2′-bis substituted nucleosides) and replacement of the ribosyl ring oxygen atom with S and further substitution at the 2-position (see published U.S. Patent Application US2005-0130923, published on Jun. 16, 2005) or alternatively 5′-substitution of a bicyclic nucleic acid (see PCT International Application WO 2007/134181, published on Nov. 22, 2007 wherein a 4′-CH₂—O-2′ bicyclic nucleoside is further substituted at the 5′ position with a 5′-methyl or a 5′-vinyl group). The synthesis and preparation of carbocyclic bicyclic nucleosides along with their oligomerization and biochemical studies have also been described (see, e.g., Srivastava et al., J. Am. Chem. Soc. 2007, 129(26), 8362-8379).

b. Certain Internucleoside Linkages

In certain embodiments, nucleosides may be linked together using any internucleoside linkage to form oligonucleotides. The two main classes of internucleoside linking groups are defined by the presence or absence of a phosphorus atom. Representative phosphorus containing internucleoside linkages include, but are not limited to, phosphodiesters (P═O), phosphotriesters, methylphosphonates, phosphoramidate, and phosphorothioates (P═S). Representative non-phosphorus containing internucleoside linking groups include, but are not limited to, methylenemethylimino (—CH₂—N(CH₃)—O—CH₂—), thiodiester (—O—C(O)—S—), thionocarbamate (—O—C(O)(NH)—S—); siloxane (—O—Si(H)₂—O—); and N,N′-dimethylhydrazine (—CH₂—N(CH₃)—N(CH₃)—). Modified linkages, compared to natural phosphodiester linkages, can be used to alter, typically increase, nuclease resistance of the oligonucleotide. In certain embodiments, internucleoside linkages having a chiral atom can be prepared as a racemic mixture, or as separate enantiomers. Representative chiral linkages include, but are not limited to, alkylphosphonates and phosphorothioates. Methods of preparation of phosphorous-containing and non-phosphorous-containing internucleoside linkages are well known to those skilled in the art.

The oligonucleotides described herein contain one or more asymmetric centers and thus give rise to enantiomers, diastereomers, and other stereoisomeric configurations that may be defined, in terms of absolute stereochemistry, as (R) or (S), α or β such as for sugar anomers, or as (D) or (L) such as for amino acids etc. Included in the antisense compounds provided herein are all such possible isomers, as well as their racemic and optically pure forms.

Neutral internucleoside linkages include without limitation, phosphotriesters, methylphosphonates, MMI (3′-CH₂—N(CH₃)—O-5′), amide-3 (3′-CH₂—C(═O)—N(H)-5′), amide-4 (3′-CH₂—N(H)—C(═O)-5′), formacetal (3′-O—CH₂—O-5′), and thioformacetal (3′-S—CH₂—O-5′).

S. Sanghvi and P. D. Cook, Eds., ACS Symposium Series 580; Chapters 3 and 4, 40-65). Further neutral internucleoside linkages include nonionic linkages comprising mixed N, O, S and CH₂ component parts.

c. Certain Motifs

In certain embodiments, the invention provides modified oligocucleotides. In certain embodiments, modified oligonucleotides comprise one or more modified sugars. In certain embodiments, modified oligonucleotides comprise one or more modified nucleobases. In certain embodiments, modified oligonucleotides comprise one or more modified internucleoside linkages. In certain embodiments, the modifications (sugar modifications, nucleobase modifications, and/or linkage modifications) define a pattern or motif. In certain embodiments, the patterns of chemical modifications of sugar moieties, internucleoside linkages, and nucleobases are each independent of one another. Thus, a modifed oligonucleotide may be described by its sugar modification motif, internucleoside linkage motif and/or nucleobase modification motif (as used herein, nucleobase modification motif describes the chemical modifications to the nucleobases independent of the sequence of nucleobases).

In certain embodiments, every sugar moiety of the modified oligonucleotides of the present invention is modified. In certain embodiments, modified oligonucleotides include one or more unmodified sugar moiety.

b. Certain Antisense Activities and Mechanisms

The 5′-UTR has emerged as playing an important role in the regulation of translation of many transcripts. In certain embodiments, the 5′-UTR contains translation suppression elements (TSEs), which serve to suppress translation of a target protein. In certain embodiments, translation suppression elements are uORFs. In certain embodiments, translation suppression elements are G-quartets. In certain embodiments, translation suppression elements are stem-loops. Disruption of a TSE will decrease the TSE's suppression of translation of a given transcript and will therefore result in an increase in translation of a target protein. In certain embodiments, antisense compounds are used to disrupt a TSE and to increase translation of a target protein.

Upstream open reading frames have emerged as an important mechanism by which translation is regulated. Approximately 50% of human transcripts have uORFs and most appear to be functional. When functional, uORFs typically reduce the translation of a polypeptide or protein from the downstream pORF. Characteristics of uORFs such as the strength of Kozak sequence and\or the distance from the 5′cap, affect the effectiveness of each uORF in reducing the translation of the downstream protein. Other factors, such as the secondary structure of the uORF or the number of uORFs per transcript also affect the effectiveness of each uORF in reducing the translation of the downstream protein. Certain embodiments of the present disclosure provide uORF inhibitors (e.g. antisense compounds) that serve to block the initiation of translation from a uORF. In certain embodiments, the uORF inhibitors do not activate RNase H. In certain such embodiments, translation of the protein encoded by a downstream ORF (e.g., the pORF) is enhanced. Certain embodiments of the present invention block the initiation of translation from a uORF with a uORF inhibitor. In certain such embodiments, translation of the protein encoded by the downstream ORF (e.g., the pORF) is enhanced. Certain embodiments of the present disclosure provide TSE inhibitors and/or uORF inhibitors (e.g. antisense compounds) that when bound to a complementary target transcript, do not activate RNase H. Certain embodiments of the present disclosure provide TSE inhibitors and/or uORF inhibitors (e.g. antisense compounds), wherein the antisense compounds are modified oligonucleotides that are not gapmers.

Upstream open reading frames can regulate translation of polypeptides or proteins encoded by pORFs by a variety of mechanisms. The polypeptide or protein encoded by the uORF may be translated, and the resulting uORF polypeptide may block translation of the polypeptide or protein encoded by the pORF on the same mRNA molecule (cis regulation) or on a separate mRNA molecule (trans regulation). In another example of cis regulation, the ribosomal subunits may dissociate from the mRNA following translation of the uORF polypeptide, thus failing to recognize and translate the pORF polypeptide or protein. Alternatively, the uORF stop codon may be recognized as a premature stop codon and initiate nonsense mediated decay. The extent to which a uORF suppresses translation of a pORF polypeptide or protein depends on how often it is recognized by the translational machinery, which is in turn affected by many factors, including the strength of the associated Kozak sequence, the number of uORFs in the 5′-UTR, the position of the stop codon, and the secondary structure of the uORF. uORF inhibitors may be employed to disrupt, alter, or exploit any of these mechanisms. In certain embodiments, uORF inhibitors are antisense compounds, and antisense compounds may be employed to disrupt, alter, or exploit any of these mechanisms. In certain embodiments, uORF inhibitors are antisense compounds, and antisense compounds may be employed to disrupt, alter, or exploit any of these mechanisms to increase expression of a target protein in a cell.

In certain embodiments, a uORF inhibitor (e.g. an antisense compound) disrupts one or more of the factors that contribute to the recognition of a uORF start site by a ribosomal subunit. In certain embodiments, a uORF inhibitor (e.g. an antisense compound) may prevent or decrease one or more of the uORF mediated translational suppressors of pORF polypeptide or protein translation discussed above. For example, in certain embodiments, a uORF inhibitor (e.g. an antisense compound) will disrupt one or more elements of a Kozak sequence, and thereby inhibit recognition of a uORF start site by a ribosomal subunit. For example, in certain embodiments, an antisense compound complementary to a portion of a uORF start site may prevent one or more ribosomal subunits from recognizing a Kozak consensus sequence. In certain embodiments, an antisense compound complementary to a portion of a uORF start site may prevent one or more ribosomal subunits from recognizing a Kozak consensus sequence and would therefore cause the ribosome to pass by the uORF start site and initiate translation at a downstream start site (e.g. the pORF start site). A uORF inhibitor (e.g. an antisense compound) would thereby increase the amount or activity of the target protein encoded by the pORF.

In certain embodiments, an antisense compound complementary to a portion of a target transcript upstream of a uORF start site may prevent one or more ribosomal subunits from recognizing a Kozak consensus sequence. In certain embodiments, an antisense compound complementary to a portion of a target transcript upstream of a uORF start site may prevent one or more ribosomal subunits from recognizing the uORF start site. In certain embodiments, an antisense compound complementary to a portion of a target transcript 10 nucleobases upstream of a uORF start site may prevent one or more ribosomal subunits from recognizing a Kozak consensus sequence. In certain embodiments, an antisense compound complementary to a portion of a target transcript 20 nucleobases upstream of a uORF start site may prevent one or more ribosomal subunits from recognizing a Kozak consensus sequence. In certain embodiments, an antisense compound complementary to a portion of a target transcript 30 nucleobases upstream of a uORF start site may prevent one or more ribosomal subunits from recognizing a Kozak consensus sequence. In certain embodiments, an antisense compound complementary to a portion of a target transcript 40 nucleobases upstream of a uORF start site may prevent one or more ribosomal subunits from recognizing a Kozak consensus sequence. In certain embodiments, an antisense compound complementary to a portion of a target transcript 50 nucleobases upstream of a uORF start site may prevent one or more ribosomal subunits from recognizing a Kozak consensus sequence. In certain embodiments, an antisense compound complementary to a portion of a target transcript 60 nucleobases upstream of a uORF start site may prevent one or more ribosomal subunits from recognizing a Kozak consensus sequence. In certain embodiments, an antisense compound complementary to a portion of a target transcript at least 60 nucleobases upstream of a uORF start site may prevent one or more ribosomal subunits from recognizing a Kozak consensus sequence. Therefore, in certain embodiments, an antisense compound complementary to a portion of a target transcript upstream of a uORF start site would increase the amount or activity the target protein encoded by the pORF.

In certain embodiments, an antisense compound complementary to a portion of a target transcript downstream of a uORF start site may prevent one or more ribosomal subunits from recognizing a Kozak consensus sequence. In certain embodiments, an antisense compound complementary to a portion of a target transcript downstream of a uORF start site may prevent one or more ribosomal subunits from recognizing the uORF start site. Therefore, in certain embodiments, an antisense compound complementary to a portion of a target transcript downstream of a uORF start site would increase the amount or activity the target protein encoded by the pORF.

In certain embodiments, disruption one or more of the factors that contribute to the recognition of a uORF start site by a ribosomal subunit by a uORF inhibitor (e.g. an antisense compound) increases expression of a downstream pORF. For example, a uORF inhibitor (e.g. an antisense compound) may prevent the dissociation of ribosomal submits after uORF polypeptide translation and thereby increase expression of a downstream pORF. For example, a uORF inhibitor (e.g. an antisense compound) may prevent the recognition of the uORF termination codon as premature and prevent nonsense-mediated decay of the transcript comprising the pORF.

In certain embodiments the ribosomal subunits recognize a uORF start site and after translation of all or part of the uORF polypeptide, the ribosomal subunits dissociate from the transcript before recognition of the pORF start site. In certain embodiments, the ribosomal subunits are the 60s ribosomal subunit and/or the 40s ribosomal subunit. In certain embodiments, a uORF inhibitor (e.g. an antisense compound) may increase the amount of translation reinitiation at the pORF after uORF polypeptide translation. For example, in certain embodiments, a uORF inhibitor (e.g. an antisense compound) prevents the amount of the 60s ribosomal subunit and/or the 40s ribosomal subunit that dissociate from the transcript after translation of all or part of the uORF polypeptide and thereby increases translation of the pORF polypeptide or protein.

In certain embodiments, a uORF inhibitor is a small molecule. In certain embodiments, a uORF inhibitor is an antibody. In certain embodiments, a uORF inhibitor is a polypeptide. In certain embodiments, a uORF inhibitor (e.g. a small molecule, antibody, polypeptide, and/or siRNA) increases the amount or activity a target protein encoded by a pORF via any of the mechanisms described herein.

Upstream open reading frames are one type of translation suppression element. In addition to uORFs, translation can be regulated by other types of translation suppression elements (TSEs) in the 5′-UTR. Translation may be suppressed by structural elements in the 5′-UTR, such as stem-loops and hairpins. In certain embodiments, the extent to which a structural element suppresses translation may be correlated with the sequence and/or stability of the structural element. For example, the extent to which a structural element suppresses translation may increase as the distance between the 5′-cap of the target transcript and the structural element decreases. For another example, in certain embodiments, GC content and/or the number of consecutive GC nucleosides in the structural element may positively correlate with the extent to which translation is suppressed, due to increased stability of the structural element. Thus, in certain embodiments, transcripts with a 5′-UTR containing multiple stretches of at least 3 consecutive GC nucleosides may comprise at least one TSE. In certain embodiments, transcripts with a 5′-UTR containing at least one stretch of at least 7 GC nucleosides may comprise at least one TSE.

TSEs that are structural elements may sterically block one or more ribosomal subunits from accessing the coding region. Without wishing to be bound by mechanism, TSE inhibitors may increase translation of a target protein by relieving such steric blockage. In certain embodiments, antisense compounds that are complementary to at least a portion of a TSE structural element alter the structure of the structural element, resulting in increased translation of the target protein. In certain embodiments, such antisense compounds unfold the structural element. In certain embodiments, antisense compounds that are TSE inhibitors have at least 60% GC content. In certain embodiments, antisense compounds that are TSE inhibitors have at least 70% GC content. In certain embodiments, antisense compounds that are TSE inhibitors have at least 80% GC content. In certain embodiments, antisense compounds that are TSE inhibitors have at least 90% GC content. In certain embodiments, antisense compounds that are TSE inhibitors have 100% GC content. In certain embodiments, antisense compounds that are TSE inhibitors have 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or at least 20 consecutive GC nucleosides. In certain embodiments, antisense compounds that are TSE inhibitors are complementary to the stem portion of a stem-loop in the 5′-UTR of the target transcript. In certain embodiments, antisense compounds that are TSE inhibitors are complementary to a hairpin in the 5′-UTR of the target transcript.

A third type of TSE is a G quartet. In certain embodiments, the extent to which a G quartet suppresses translation may increase as the distance between the 5′-cap of the target transcript and the G quartet decrases.

A fourth type of TSE is a stem-loop structure. In certain embodiments, transcripts having a stem-loop structure within the 5′-UTR suppress translation of the target protein. In certain embodiments, the extent to which a stem-loop suppresses translation may increase as the distance between the 5′-cap of the target transcript and the stem-loop decrases.

d. Certain Compositions and Methods for Decreasing Antisense Activity

In certain embodiments, antisense compounds disclosed herein may target microRNAs or other naturally occurring non-coding transcripts that are complementary to a uORF region or a translation suppression element. Certain such antisense compounds would therefore inhibit expression of a target transcript by increasing the effect of a translation suppression element or uORF. For example, in certain embodiments, a non-coding transcript, such as a microRNA may be complementary to a uORF or uORF region and serve to increase expression of a target protein. An antisense compound complementary to the microRNA would sequester the microRNA and the uORF would then suppress translation of the target protein. In such a manner, an antisense compound would inhibit expression of a target protein.

C. Certain Target Genes

The present disclosure provides compounds and methods that may be used to increase expression of any target protein, provided there is at least one uORF on a transcript encoding the target protein. The present disclosure also provides compounds and methods that may be used to increase expression of any target protein, provided there is at least one TSE on a transcript encoding the target protein. In certain embodiments, the at least one TSE comprises a uORF. In certain embodiments, there are at least two TSEs on a transcript encoding a target protein. In certain embodiments neither of the at least two TSEs comprise a uORF. In certain embodiments, one of the at least two TSEs comprises a uORF. In certain embodiments, both of the at least two TSEs comprise a uORF. In certain embodiments, a deficiency of the target protein is associated with disease and so increasing the amount or activity of the protein is expected to ameliorate one or more symptoms of the disease or delay the onset of one or more symptoms of the disease. Table 1 and Table 2, below, list certain genes and associated diseases. In certain embodiments, a target transcript is encoded by a gene listed in Table 1 or Table 2. In certain embodiments, the associated disease or disorder in Table 1 or Table 2 is treated by use of an antisense compound of the present invention targeting such transcript. The diseases associated with each gene in Table 1 include diseases that arise due to or are correlated with an insufficiency of the corresponding uORF-containing gene as well as diseases that could be ameliorated by up-regulation of the corresponding uORF-containing gene. The diseases associated with each gene in Table 2 include diseases that correlate with a mutation or SNP that introduces a uORF in the corresponding gene.

In certain embodiments, antisense compounds are targeted to one or more TSEs in the 5′UTR of a gene in Table 1 or Table 2. In certain embodiments, antisense compounds are not targeted to one or more TSEs in the 5′UTR of a gene in Table 1 or Table 2.

Nonlimiting Disclosure and Incorporation by Reference

While certain compounds, compositions and methods described herein have been described with specificity in accordance with certain embodiments, the following examples serve only to illustrate the compounds described herein and are not intended to limit the same. Each of the references, GenBank accession numbers, and the like recited in the present application is incorporated herein by reference in its entirety.

Although the sequence listing accompanying this filing identifies each sequence as either “RNA” or “DNA” as required, in reality, those sequences may be modified with any combination of chemical modifications. One of skill in the art will readily appreciate that such designation as “RNA” or “DNA” to describe modified oligonucleotides is, in certain instances, arbitrary. For example, an oligonucleotide comprising a nucleoside comprising a 2′-OH sugar moiety and a thymine base could be described as a DNA having a modified sugar (2′-OH for the natural 2′-H of DNA) or as an RNA having a modified base (thymine (methylated uracil) for natural uracil of RNA).

Accordingly, nucleic acid sequences provided herein, including, but not limited to those in the sequence listing, are intended to encompass nucleic acids containing any combination of natural or modified RNA and/or DNA, including, but not limited to such nucleic acids having modified nucleobases. By way of further example and without limitation, an oligomeric compound having the nucleobase sequence “ATCGATCG” encompasses any oligomeric compounds having such nucleobase sequence, whether modified or unmodified, including, but not limited to, such compounds comprising RNA bases, such as those having sequence “AUCGAUCG” and those having some DNA bases and some RNA bases such as “AUCGATCG” and oligomeric compounds having other modified or naturally occurring bases, such as “AT^(m)CGAUCG,” wherein ^(m)C indicates a cytosine base comprising a methyl group at the 5-position.

EXAMPLES

The following examples illustrate certain embodiments of the present invention and are not limiting. Moreover, where specific embodiments are provided, the inventors have contemplated generic application of those specific embodiments. For example, disclosure of an oligonucleotide having a particular motif provides reasonable support for additional oligonucleotides having the same or similar motif And, for example, where a particular high-affinity modification appears at a particular position, other high-affinity modifications at the same position are considered suitable, unless otherwise indicated.

Example 1: Effects of Antisense Oligonucleotides Targeting the uORF of RNase H1 on RNase H1 Protein Expression

Human RNase H1 mRNA (GENBANK accession number NM_001286834.1, designated herein as SEQ ID NO: 1) comprises an upstream open reading frame (uORF). Antisense oligonucleotides designed to target the start codon of the uORF of human RNase H1 were tested for their effects on RNase H1 expression in vitro. These antisense oligonucleotides, described in Table 3, were uniformly modified in order to avoid inducing cleavage of the target RNA. The start and stop sites listed in Table 3 indicate the positions on SEQ ID NO: 1 that the antisense oligonucleotides target. The targeted uORF begins at position 86. HeLa cells were transfected with Lipofectamine RNAiMAX (Life Technologies) and one of the antisense oligonucleotides at a final concentration of 25 nM or were mock transfected as a control. Thirty hours after transfection, the cells were lysed, and expression of RNase H1 was analyzed by western blot and RT-PCR. The primary antibody used for the western blot was made as described in Wu et al. Determination of the Role of the Human RNase H1 in the Pharmacology of DNA-like Antisense Drugs. J. Biol. Chem. 279, 17181 (2004), and the secondary antibody was purchased from Biorad (catalog #170-6515). The western blot was quantified using Image J, and the results are shown in Table 3 as percent protein levels relative to mock transfected cells following normalization to the Annexin A2 loading control. The RT-PCR results are shown in Table 3 as percent mRNA levels relative to mock transfected cells following normalization to Ribogreen. The results show that antisense oligonucleotides targeting a portion of the RNase H1 uORF that includes the uORF start codon increased RNase H1 expression. Furthermore, certain antisense oligonucleotides did not significantly affect RNase H1 mRNA levels, indicating that the increased RNase H1 expression exhibited by those oligonucleotides occurred mainly via increased translation.

Example 2: Time Course of RNase H1 Protein Expression Following Treatment with an Antisense Oligonucleotide Targeting the uORF In Vitro

HeLa cells were transfected with 25 nM Isis No. 761909 (see Table 3). At various time points following transfection, the cells were harvested and RNase H1 expression was analyzed by western blot as described in Example 1. The results are shown in Table 4 as the percent RNase H1 protein expression relative to cells that did not receive antisense oligonucleotide treatment (harvested at the 0 hour time point) following normalization to the Annexin A2 loading control. The results show that the induction of RNase H1 expression was observed within 4 hours following transfection, and maximal expression was observed at approximately 12 hours following transfection.

Example 3: Dose Response Effect of an Antisense Oligonucleotide Targeting the uORF of RNase H1 on RNase H1 Protein Expression In Vitro

Isis No. 761909 (see Table 3) was tested at five different doses for its effect on RNase H1 expression in vitro. HeLa cells were transfected with 761909 at a concentration listed in Table 5 or were not treated as a control. Fifteen hours after transfection, RNase H1 expression was analyzed as described in Example 1. The results are shown in Table 5 as the percent protein levels relative to untreated control cells following normalization to the Annexin A2 loading control and as mRNA levels relative to untreated control cells following normalization to Ribogreen. The results show that an antisense oligonucleotide targeting a portion of the RNase H1 uORF increased RNase H1 protein levels in a dose dependent manner; and mRNA levels did not increase, indicating that the antisense oligonucleotide increased RNase H1 expression via increased translation.

Example 4: Effects of Antisense Oligonucleotides Targeting the 5′-Untranslated Region Upstream of the RNase H1 uORF on RNase H1 Protein Expression

Antisense oligonucleotides designed to target the 5′-untranslated region upstream of the uORF of human RNase H1 were tested for their effects on RNase H1 protein expression in vitro. These antisense oligonucleotides, described in Table 6, were uniformly modified in order to avoid inducing cleavage of the target RNA. The start and stop sites listed in Table 6 indicate the positions on SEQ ID NO: 1 that the antisense oligonucleotides target. Isis 761909 was included for reference. HeLa cells were transfected with 20 nM antisense oligonucleotide or were mock transfected as a control. Fifteen hours after transfection, RNase H1 expression was analyzed as described in Example 1. The results are shown in Table 6 below as percent protein expression relative to mock transfected cells following normalization to the γ-tubulin loading control and percent mRNA levels relative to mock transfected cells following normalization to Ribogreen. The results show that antisense oligonucleotides do not necessarily need to target the start codon of an uORF in order to induce increased translation of the target. Antisense oligonucleotides that target the 5′-untranslated region upstream of an uORF and antisense oligonucleotides that target at least a portion of the uORF itself can induce translation of the target. Furthermore, the antisense oligonucleotides targeting the 5′-untranslated region upstream of the uORF did not increase mRNA levels, indicating that they increased RNase H1 expression via increased translation.

Example 5: Effects of Antisense Oligonucleotides of Varying Lengths on RNase H1 Protein Expression

Antisense oligonucleotides of varying lengths designed to target at least a portion of the uORF of human RNase H1 were tested for their effects on RNase H1 expression in vitro. These antisense oligonucleotides, described in Table 7, were uniformly modified in order to avoid inducing cleavage of the target RNA. The start and stop sites listed in Table 7 indicate the positions on SEQ ID NO: 1 that the antisense oligonucleotides target. HeLa cells were transfected with 20 nM antisense oligonucleotide or were mock transfected as a control. Fifteen hours after transfection, RNase H1 expression was analyzed as described in Example 1. The results are shown in Table 7 below as the percent protein expression relative to mock transfected cells following normalization to the γ-tubulin loading control and percent mRNA levels relative to mock transfected cells following normalization to Ribogreen. The results show that antisense oligonucleotides of various lengths increased RNase H1 expression mainly via increased translation of the target.

Example 6: Effects of Antisense Oligonucleotides Targeting the uORF of Mouse LRPPRC on LRPPRC Protein Expression

Mouse Leucine-Rich PPR-Motif Containing (LRPPRC) mRNA (GENBANK accession number NM_028233.2, designated herein as SEQ ID NO: 2) comprises an upstream open reading frame. Antisense oligonucleotides with various lengths and internucleoside linkages designed to target the start codon of the uORF of mouse LRPPRC were tested for their effects on LRPPRC protein expression in vitro. These antisense oligonucleotides, described in Table 8, were uniformly modified in order to avoid inducing cleavage of the target RNA. The start and stop sites listed in Table 8 indicate the positions on SEQ ID NO: 2 that the antisense oligonucleotides target. The targeted uORF begins at position 70. MHT cells were transfected with Lipofectamine RNAiMAX (Life Technologies) and an antisense oligonucleotide at a concentration listed in Table 8 or were untreated as a control. Fifteen hours after transfection, the cells were lysed, and a western blot was performed with an LRPPRC antibody purchased from Abcam (catalog #ab97505) to analyze expression of LRPPRC. The western blot was quantified using Image J, and the results are shown in Table 8 below as the percent expression relative to untreated control cells following normalization to the loading control (Annexin A2 for 761932 and 761933, and hnRNP K for 759704 and 761930). The results show that antisense oligonucleotides of various lengths targeting the start codon of the uORF of mouse LRPPRC increased LRPPRC expression, including oligonucleotides comprising phosphodiester internucleoside linkages and an oligonucleotide comprising phosphorothioate internucleoside linkages. Thus, the results in Table 8 along with the results in the Examples above show that various antisense oligonucleotides targeting at least a portion of an uORF can increase expression of multiple targets in multiple species.

Example 7: Effect of Antisense Oligonucleotide Targeting the uORF of Human SFXN3 on SFXN3 Protein Expression

Human Sideroflexin 3 (SFXN3) mRNA (GENBANK accession number NM_030971.3, designated herein as SEQ ID NO: 20) comprises an upstream open reading frame. An antisense oligonucleotide designed to target the start codon of the uORF of human SFXN3 was tested for its effect on SFXN3 protein expression in vitro. The antisense oligonucleotide, described in Table 9, was uniformly modified in order to avoid inducing cleavage of the target RNA. The start and stop sites listed in Table 9 indicate the positions on SEQ ID NO: 20 that the antisense oligonucleotide targets. The targeted uORF begins at position 388. HeLa cells were transfected with Lipofectamine RNAiMAX (Life Technologies) and an antisense oligonucleotide at a concentration listed in Table 9 or were untreated as a control. Ten hours after transfection, the cells were lysed, and SFXN3 mRNA and protein expression were analyzed by RT-PCR and western blot, respectively. The western blot was performed with an SFXN3 antibody purchased from Abcam (catalog #ab181163) and quantified using Image J. The results are shown in Table 9 below as the percent protein expression relative to untreated control cells (“UTC”) following normalization to the loading control (Ku70, detected with Abcam antibody, catalog #ab3114). SFXN3 mRNA levels normalized to Ribogreen are also shown. The results show that an antisense oligonucleotide targeting the start codon of the uORF of human SFXN3 increased SFXN3 protein expression. SFXN3 mRNA levels did not increase, indicating that the antisense oligonucleotide increased SFXN3 expression via increased translation.

Example 10: Effects of Mismatched Antisense Oligonucleotides Targeting the uORF of RNase H1 on RNase H1 Protein Expression

Antisense oligonucleotides designed to target the start codon of the uORF of human RNase H1 with two mismatches between the antisense oligonucleotide and the target sequence were tested for their effects on RNase H1 expression in vitro. These antisense oligonucleotides, described in Table 12, were uniformly modified in order to avoid inducing cleavage of the target RNA. The start and stop sites listed in Table 12 indicate the positions on SEQ ID NO: 1 that the antisense oligonucleotides target, and the mismatched nucleotides are bolded. The targeted uORF begins at position 86. HeLa cells were transfected with Lipofectamine RNAiMAX (Life Technologies) and an antisense oligonucleotide at a final concentration of 25 nM or were mock transfected as a control. Twenty-four hours after transfection, the cells were lysed, and expression of RNase H1 was analyzed by western blot as described in Example 1. The results are shown in Table 12 as percent protein levels relative to mock transfected cells following normalization to the Ku70 loading control. The results show that antisense oligonucleotides with mismatches to the uORF start codon or near to the uORF start codon had little to no effect on RNase H1 protein expression, whereas antisense oligonucleotides with mismatches further away from the uORF start codon increased RNase H1 protein expression.

Example 11: Effects of Antisense Oligonucleotides Comprising Various Modifications

Antisense oligonucleotides targeting the start codon of the uORF in human RNase H1 (SEQ ID NO: 1) or mouse LRPPRC (SEQ ID NO: 2) were designed with various lengths and with various modifications to the intemucleoside linkages and to the sugars. These antisense oligonucleotides were tested for their effects on target protein expression in vitro. HEK293 cells (RNase H1 targeting oligonucleotides) or MHT cells (LRPPRC targeting oligonucleotides) were transfected with Lipofectamine RNAiMAX (Life Technologies) and an antisense oligonucleotide at a concentration listed in the tables below. Ten hours after transfection, the cells were lysed, and target protein expression was analyzed by western blot as described in Example 1 (for RNase H1) or Example 6 (for LRPPRC). The results are shown in the tables below as the percent protein expression relative to untreated control cells (“UTC”) following normalization to the loading control (Ku70, γ-tubulin, Annexin A2, or a non-specific band detected by the primary antibody). The results show that antisense oligonucleotides of various lengths and with modified internucleoside linkages and various 2′-modifications and bicyclic nucleosides increased target protein expression.

Example 12: Effects of Antisense Oligonucleotides Targeting the uORF of Mouse LRPPRC In Vivo

Isis No. 761933 (see Example 6) was tested for its effect on LRPPRC protein expression in vivo. Groups of three or four male, seven week old BALB/c mice were systemically administered Isis No. 761933, at a dose listed in the tables below, or saline by subcutaneous injection. Animals were sacrificed (Table 23) or received a second dose (Table 24) 48 hours later. Animals that received a second dose were sacrificed 48 hours after the second dose. Liver homogenates were prepared, and LRPPRC protein expression was analyzed by western blot, as described in Example 6. The results are shown in the tables below as the percent expression relative to saline treated animals following normalization to the loading control (GAPDH or hnRNP K). The results show that LRPPRC protein expression was increased in vivo following treatment with an antisense oligonucleotide targeting the LRPPRC uORF.

Bone marrow THPO mRNA levels were unaffected by the antisense oligonucleotide treatment (data not shown). The results shown in the table below are the average of two independent experiments and are shown as the percent expression relative to saline treated animals following normalization to the loading control (Transferrin). The results show that THPO protein expression was increased in vivo following treatment with an antisense oligonucleotide targeting the THPO uORF.

Example 14: Inhibition of a uORF Targeting Oligonucleotide with a Complementary Oligonucleotide

In order to test whether increased translation that is mediated by an oligonucleotide targeting a uORF could be reversed, the effect of an oligonucleotide complementary to the uORF targeting oligonucleotide was tested in vitro. HeLa cells were transfected with 20 nM of Isis No. 761909, as described in Example 1. Five hours later, the cells were transfected with a concentration of Isis No. 761929, which is complementary to Isis No. 761909, listed in the table below. Five hours after the second transfection, cells were lysed and RNase H1 protein expression was analyzed as described in Example 1, with γ-tubulin used as the loading control. The results are shown in the table below as the percent expression relative to mock transfected cells following normalization to the γ-tubulin loading control. The results show that an oligonucleotide targeted to a uORF targeting oligonucleotide blocked the uORF targeting oligonucleotide's ability to increase translation in a dose dependent manner.

Example 15: Inhibition of a uORF Targeting Oligonucleotide by Globally Blocking Translation

In order to test whether increases in protein expression mediated by antisense oligonucleotides targeting a uORF are due to increased protein stability, translation was blocked following transfection of the oligonucleotide. HeLa cells were transfected with Isis No. 761909 (see Example 1) or mock transfected. Twelve hours later, cells were treated with DMSO or 15 μg/ml cycloheximide at 37° C. Cells were then collected at various time points and cell lysates were prepared and subjected to western analysis, as described in Example 1. A duplicate SDS-PAGE gel was silver-stained and served as loading control. RNase H1 protein levels were calculated relative to mock transfected cells following normalization to the loading control. The results (data not shown) showed that the rates of reduction of RNase H1 protein levels following cycloheximide treatment were similar for mock and Isis No. 761909 transfected cells. Thus, these results, along with the lack of increase in mRNA shown in several above examples, show that increases in protein expression mediated by antisense oligonucletoides targeting a uORF are due to increased protein translation.

Example 16: Effect of a uORF Targeting Antisense Oligonucleotide on Nascent Protein Translation

In order to further confirm that antisense oligonucleotides targeting a uORF mediate an increase in translation of new protein, pulse-chase labeling and immunoprecipitation of LRPPRC was performed. MHT cells were transfected with Isis No. 761930 for 7 hours, and incubated with pre-warmed medium lacking methionine (Invitrogen, RPMI 1640) at 37° C. for 30 minutes. Cells were then pulse-labeled with 35 μCi/ml S³⁵-methionine in RPMI1640 medium for 20 minutes and chased with 1 mM methionine for 40 minutes. Cells were washed with cold PBS containing 10 μg/ml cycloheximide and cell lysate were prepared using IP buffer (Life Technologies). Immunoprecipitation was conducted using anti-LRPPRC antibody (Proteintech) at 4° C. for 3 hours. After 4 washes, the precipitated proteins were analyzed on a 4-12% SDS-PAGE gel, transferred to a membrane, and visualized by autoradiography. The LRPPRC band in the immunoprecipitate from the mock treated cells was significantly lighter than in the immunoprecipitate from the Isis No. 761930 treated cells (data not shown), further confirming that antisense oligonucleotides targeting a uORF increase protein expression via increasing target protein translation. Furthermore, the lysate inputs for both the mock and Isis No. 761930 transfected cells were also analyzed via autoradioagraphy and were very similar, indicating that the increased translation was target specific.

Example 17: Effect of an Antisense Oligonucleotide Targeting the uORF of RNase H1 on RNase H1 Activity

In order to test whether the increase in RNase H1 protein levels mediated by antisense oligonucleotides targeting a RNase H1 uORF results in an increase in RNase H1 activity, cells were first transfected with Isis No. 761909 (see Example 1) or a control oligonucleotide that does not target RNase H1, Isis No. 759704, then transfected with an antisense oligonucleotide targeting U16 snoRNA or NCL1 mRNA. Ten hours after the first transfection, the cells were reseeded at approximately 50% confluency. Cells were transfected a second time 14 hours later with Isis No. 462026 (U16) or Isis No. 110074 (NCL1) for an additional 4 hours. Cells were then collected, lysed, and U16 snoRNA or NCL1 mRNA levels were analyzed by RT-qPCR using TaqMan primer probe sets. The primer probe set sequences used were: Forward: 5′-CTTGCAATGATGTCGTAATTTGC-3′, SEQ ID NO: 46, Reverse: 5′-TCGTCAACCTTCTGTACCAGCTT-3′, SEQ ID NO: 47, and Probe: 5′-TTACTCTGTTCTCAGCGACAGTTGCCTGC-3′, SEQ ID NO: 48 for U16; and Forward: 5′-GCTTGGCTTCTTCTGGACTCA-3′, SEQ ID NO: 49, Reverse: 5′-TCGCGAGCTTCACCATGA-3′, SEQ ID NO: 50, and Probe: 5′-CGCCACTTGTCCGCTTCACACTCC-3′, SEQ ID NO: 51 for NCL1. The results are shown in the tables below as the percent RNA levels relative to untreated control cells that were not transfected with any oligonucleotide, normalized to total RNA as measured using Ribogreen. The results show that Isis No. 761909 targeting a RNase H1 uORF increased the antisense activity of U16 and NCl1 antisense oligonucleotides.

Example 18: Effects of Antisense Oligonucleotides Targeting the 5′-Untranslated Region of RNase H1

Antisense oligonucleotides designed to target the 5′-untranslated region upstream of the uORF of human RNase H1 were tested for their effects on RNase H1 protein expression in vitro. The start and stop sites listed in the tables below indicate the positions on SEQ ID NO: 1 that the antisense oligonucleotides target. HEK 293 cells were transfected with 20 nM antisense oligonucleotide or were mock transfected as a control. Ten hours after transfection, RNase H1 protein expression was analyzed as described in Example 1. The results are shown in the tables below as percent protein expression relative to mock transfected cells following normalization to the GAPDH loading control. The results show that many antisense oligonucleotides targeting the 5′-untranslated region upstream of the RNase H1 uORF induced translation of the target.

Example 19: Effects of Antisense Oligonucleotides Targeting the 5′-Untranslated Region of ACP1

Antisense oligonucleotides designed to target the 5′-untranslated region of cytoplasmic phosphotyrosine protein phosphatase (ACP1), which does not comprise a uORF, were tested for their effects on ACP1 protein expression in vitro. The antisense oligonucleotides target the human ACP1 mRNA (GENBANK accession number NM_004300.3, designated herein as SEQ ID NO: 78) and were designed to target at least one stem loop structure in the 5′-untranslated region. The start and stop sites listed in the table below indicate the positions on SEQ ID NO: 78 that the antisense oligonucleotides target. HEK 293 cells were transfected with a concentration of antisense oligonucleotide shown in the table below or were not transfected as a control. Ten hours after transfection, ACP1 protein expression was analyzed by western blot using an Abcam antibody to ACP1 (catalog #ab166896). The results are shown in the tables below as percent protein expression relative to untreated control cells following normalization to the p32 loading control. The results show that the antisense oligonucleotides targeting the 5′-untranslated region of human ACP1 induced translation of the target.

Example 20: Effects of Antisense Oligonucleotides Targeting the 5′-Untranslated Region Downstream of the CFTR uORF Start Codon on CFTR Protein Expression

Antisense oligonucleotides designed to target the 5′-untranslated region downstream of the uORF start codon of human cystic fibrosis transmembrane conductance regulator (CFTR) were tested for their effects on CFTR protein expression in vitro. These antisense oligonucleotides, described in the table below, were designed to target the CFTR mRNA (GENBANK accession number NM_000492.3, designated herein as SEQ ID NO: 81) and were uniformly modified in order to avoid inducing cleavage of the target RNA. The start and stop sites listed in the table below indicate the positions on SEQ ID NO: 81 that the antisense oligonucleotides target. One uORF begins at position 13 of SEQ ID NO: 81. Isis No. 786455 targets a portion of the uORF that is just downstream of the uORF start codon. Isis No. 786456 targets a stem loop structure further downstream.

HT-29 cells were transfected with a concentration of antisense oligonucleotide listed in the table below or were mock transfected as a control. Twelve or twenty-two hours after transfection, CFTR expression was analyzed by western blot using Anti-CFTR purchased from EMD Millipore (catalog #05-583, clone M3A7). The results are shown in the table below as percent protein expression relative to mock transfected cells following normalization to the HSP90 loading control. The results show that the antisense oligonucleotides increased CFTR protein expression.

Example 21: Identification of a Translation Suppression Element that does not Comprise a uORF

In order to test the effect of portions of the RNase H1 5′-UTR sequence on RNase H1 expression, the wild type and mutant 5′-UTR sequences were cloned into a plasmid and fused to firefly luciferase. Renila luciferase was cloned into the same plasmids for normalization. The plasmids were transfected into HeLa cells and firefly and Renila luciferase activities were detected using standard methods. The mutants and their firefly luciferase activity relative to the wild type 5′-UTR reporters, normalized to Renila luciferase activity, are shown in the table below. The nucleotide positions reported in the table below refer to the positions of the 5′-UTR of SEQ ID NO: 1 that were mutated or deleted. The results are the averages of multiple experiments and show that the mutation and/or deletion of portions of the 5′-UTR sequence of RNase H1, including portions that do not comprise a uORF, resulted in increased expression in a reporter system, indicating that the mutated portions are part of a translation suppression element.

Isis No. 806740 (see Example 11) was tested for its effect on LRPPRC protein expression in vivo. Groups of three, male, seven week old BALB/c mice were systemically administered Isis No. 806740, at a dose listed in the table below, or saline by subcutaneous injection. 48 hours later, the mice received a second dose listed in the table below. Animals were sacrificed 48 hours after the second dose. Liver homogenates were prepared, and LRPPRC protein expression was analyzed by western blot, as described in Example 6. The results are shown in the tables below as the percent expression relative to saline treated animals following normalization to the loading control (PSF). The results show that LRPPRC protein expression was increased in vivo following treatment with an antisense oligonucleotide targeting the LRPPRC uORF and comprising bicyclic nucleic acids.
